Translate your text using Google Api's

  • Article

Here is how you can translate a Text using Google's "Unofficial" API's.

The URL for Google Translate is - https://www.google.com/translate\_t?hl=en\&ie=UTF8\&text={0}\&langpair={1}

  • "text" is your input string which needs to be translated.
  • langpair is the language pairs involved in the tranlsation. E.g. "ar|en" means translate from Arabic to English.

The result when you browse to the URL is a HTML page. You will have to do screen scraping to get your translated text.

Below is a C# function which translates, scrapes and gives you the result. I am using String.Substring function but you can use Regex too.

/// <summary>

/// Translate Text using Google Translate API's

/// Google URL - https://www.google.com/translate\_t?hl=en\&ie=UTF8\&text={0}\&langpair={1}

/// </summary>

/// <param name="input">Input string</param>

/// <param name="languagePair">2 letter Language Pair, delimited by "|".

/// E.g. "ar|en" language pair means to translate from Arabic to English</param>

/// <returns>Translated to String</returns>

public string TranslateText(

    string input,

    string languagePair)

{

    string url = String.Format("https://www.google.com/translate_t?hl=en&ie=UTF8&text={0}&langpair={1}", input, languagePair);

    WebClient webClient = new WebClient();

    webClient.Encoding = System.Text.Encoding.UTF8;

    string result = webClient.DownloadString(url);

    result = result.Substring(result.IndexOf("id=result_box") + 22, result.IndexOf("id=result_box") + 500);

    result = result.Substring(0, result.IndexOf("</div"));

    return result;

}

    Sorry I dont know much about VBA Excel. But, here is the same code in VB.Net -    ''' <summary>    ''' Translate Text using Google Translate API's    ''' Google URL - http://www.google.com/translate_t?hl=en&ie=UTF8&text={0}&langpair={1}    ''' </summary>    ''' <param name="input">Input string</param>    ''' <param name="languagePair">2 letter Language Pair, delimited by "|".    ''' E.g. "ar|en" language pair means to translate from Arabic to English</param>    ''' <returns>Translated to String</returns>    Public Function TranslateText(ByVal input As String, ByVal languagePair As String) As String        Dim url As String = [String].Format("http://www.google.com/translate_t?hl=en&ie=UTF8&text={0}&langpair={1}", input, languagePair)        Dim webClient As New System.Net.WebClient()        webClient.Encoding = System.Text.Encoding.UTF8        Dim result As String = webClient.DownloadString(url)        result = result.Substring(result.IndexOf("id=result_box") + 22, result.IndexOf("id=result_box") + 500)        result = result.Substring(0, result.IndexOf("</div"))        Return result    End Function You could create a COM Callable Wrapper around the class which has this method and use that with VBA.

    Does anyone know how to use Google API to translate from classic ASP?   Google Translation is working beautifully on my site for languages beyond English but it translates the values in my dropdown values which are used for searching the database, therefore all searches fail since the database values are in English. I was hoping to find a javascript method of Google API (NOT PHP) that would convert a value I pass it back to English.

    For Javascript, you can use XmlHttpRequest in place of WebClient() to call Google's API and perform the translation logic. Check back in a few days I will post sample code to be used from Javascript.

    Thanks Piyush, I got the correction....Now it's working fine. I have one more query for you. In TranslateText(Me.txt.Text, "en|ar") > "en|ar" will be sort of hard coded thing. Can we change it Dynamically? On language selection..

    Mayur, Make sure your web.config has the information of your proxy server - <system.net>    <defaultProxy>      <proxy           usesystemdefault="False"           proxyaddress="http://proxyserver:port"           bypassonlocal="True"     />    </defaultProxy>  </system.net>

    Hi :) I have tried your function to translate English into Vietnamese. But it doesn't display well. Example: Input text is 'type words you want to translate here...' The result is 'Ki&#7875;u ch&#7919; m b&#7841;n mu&#7889;n d&#7883;ch t&#7841;i &#273;y ...' (The right result must be: 'Kiểu chữ mà bạn muốn dịch tại đây...') I know the charset of the webResponse is 'ISO-8859-1', how can I set it to UTF8 ? Can you give me an advise? Thank you so much. Wish you have fun!
